We present a theory of van der Waals (vdW) atom-surface attraction in which the second order vdW energy is explicitly exhibited as a correlation/self-energy of atomic electrons generated by a dynamic, nonlocal image potential due to polarization of the electrons of the bounded metal-semiconductor surface system in the electrostatic limit. This formulation is applied to a metal/semiconductor pla...

Atomic magnetometers have found widespread applications in precise measurement of the Earth’s magnetic field due to their high sensitivity. In these measurements, various methods have been utilized to compensate the Earth’s magnetic field in an unshielded environment. In this paper, we have proposed a method based on finding the minimum resonance frequency (corresponding to minimum magnetic fie...

Targeted hyperthermia treatment using magnetic nanoparticles is a promising cancer therapy. However, the mechanisms of heat dissipation in the large alternating magnetic field used during such treatment have not been clarified. In this study, we numerically compared the magnetic loss in rotatable nanoparticles in aqueous media with that of non-rotatable nanoparticles anchored to localised struc...

The instability of longitudinal electro-kinetic wave that is propagating across the magnetic field B0 in ion-implanted group-IV semiconductor sample consisting of non-drifting electrons, holes, and negatively charged colloids is investigated. Using hydrodynamic approach, a compact dispersion relation D(ω, k) is derived for the same. The propagation and amplification characteristics of the wave ...

The recent discovery of the quantum nonlinear Hall effect has revived field transport. Here, we investigate magnetic-field-induced transport in time reversal symmetric Weyl semimetals. We show that interplay band-geometric quantities, such as Berry curvature, and magnetic part Lorentz force can give rise to finite conductivity is linear field. In addition, chiral chemical potential which repres...

We report on attempts to measure the magnetic field of the pulsating B star ν Eridani with the Musicos spectropo-larimeter attached to the 2m telescope at the Pic du Midi, France. This object is one of the most extensively studied stars for pulsation modes, and the existence of a magnetic field was suggested from the inequality of the frequency separations of a triplet in the stars' oscillation...
